Shaofeng SHI commented on KYLIN-2937:
-------------------------------------
“ StorageCleanupJob” won't clean the dict files;
Run $KYLIN_HOME/bin/metastore.sh clean --delete
This will remove the useless metadata entries, includes dictionary, snapshots,
etc. Take a backup before run this is recommended

> 非分区的cube构建之后,中间数据不会被清理.
> 存放在hdfs上的字典文件,会一直累积.cube构建时会加载所有这些累积字典文件,
> 有可能导致内存溢出(如果字典文件够大够多的话).
> For nonpartition cube will remain dictionary files which store in hdfs ,as
> kylin cube building job may
> load all dictionary files , this may make jvm heap out of memory.
